Abstract

Lithium 8 is a short lived beta emitter producing a highenergy anti-neutrino,which is very suitable formaking severalmeasurements of fundamental quantities. It is proposedto produce Lithium 8 with a commercially available60 MeV cyclotron using protons or alpha particles on aBeryllium 9 target. We have used the GEANT4 programto model these processes, and calculate the anti-neutrinofluxes that could be obtained in a practical system. We alsocalculate the production of undesirable contaminants suchas Boron 8, and show that these can be reduced to a verylow level.
